[PATCH] kill SET_LINKS/REMOVE_LINKS
Both SET_LINKS() and SET_LINKS/REMOVE_LINKS() have exactly one caller, and these callers already check thread_group_leader(). This patch kills theese macros, they mix two different things: setting process's parent and registering it in init_task.tasks list. Callers are updated to do these actions by hand.
